Title: Apron of synthetic film for endovesicular operations - has extension forming collector for rinsing and body fluids
Inventor: SCHENZ LUDWIG
IPC: A61B46/00
Filed: 1976-01-14
Abstract: An apron for endovesicular operations has at its bottom end, an extension which can be fastened to the operating table. It thus forms a collector for rinsing fluids, and a drain pipe is provided to load the liquids away to a container.

Title: Automatic opening of filter press for cake discharge - having moving grab with eccentric rotor to move one plate at a time
Inventor: LINSER JOERG PROF
IPC: B01D25/172
Filed: 1976-06-19
Abstract: Plates of filter press are broken from bundle and moved one at a time to discharge the cake collected between them. This is done by a moving grab which can be coupled with each individual plate. This grab consists of a distance piece which retains the next plate in position until the plate being moved is out of the way. Its effective length varies in the direction of the push. Each plate has a projection extending into the region of movement of the grab. The distance piece consists of an eccentrically pivotted curved plate. From this extend projections on the same curve as the plate, running eccentrically around the axis of rotation of the grav. These are in the form of free moving rollers. The spacing between the axis of the rollers and the axis of rotation of the grab is gradually increased around the plate. Used on filter presses, for automatic cake discharge. Adhesion between plates is avoided in the device because the grab holds the next plate in position while pulling away the first plate in the bundle.

Title: Totally enclosed folding box making appts. - uses two pairs of rollers with two sets of cutting knives
Inventor: WILLIAMS DONALD FRANKLIN
IPC: B65D5/66
Filed: 1977-06-30
Abstract: The folding box totally enclosed and made from one piece is made from a flat blank brought to the shape required and a correspondingly formed flat covering. The blank and its covering are convergingly guided between the first pair of rollers and subsequently the second pair of rollers. Between a first cutting knife and the combined cut out and covering a relative movement is carried out so that the cutting knife makes a linear cut on the side of the covering in the direction of movement of both cut out and covering. Following this a further relative movement is produced between a second cutting knife and the cut out with a covering to make a second linear cut which crosses the first cut. Then the run though of cut out and covering are reversed.
